Embodiment Construction

[0018] The present invention is described in detail in conjunction with accompanying drawings.

[0019] Such as figure 1 As shown, a complexed mancozeb top-spray drying method, the complexed slurry enters the spray drying tower 3 and is atomized in the spray drying tower 3 by compressed air, and is heated with the heated air. After mass exchange, the dried dry material is separated by the cyclone separator 5 and then enters the dry product bin 9, and a small amount of unseparated material is captured by the bag filter and enters the dry product bin 9 to obtain a complex state Mancozeb wettable powder, the slurry with good complexation reaction enters from the top of the spray drying tower 3, and moves downward in the spray drying tower 3 in a swirling flow. The drying temperature is 200-230°C, and the pressure of compressed air is 0.4MPa. ~0.6MPa, the outlet temperature of the spray drying tower 3 is ≤80°C, the angle at which the material comes out of the atomizer 2 during a...

Abstract

The invention discloses a complexation type mancozeb top-jet-type drying method. In the invention, sizing agents after complex reaction enter from the top of a spray drying tower, and move downwards in a rotational flow mode in the spray drying tower; the drying temperature is 230 DEG C, the pressure of compressed air is from 0.4 MPa to 0.6 MPa, and the outlet temperature of the spray drying tower is less than or equal to 80 DEG C; and the angle of the materials coming out of an atomizer during atomization is from 50 degrees to 60 degrees. Atmosphere is communicated to an inlet of a heat interchanger, an outlet is connected with an inlet of the spray drying tower, an outlet of the spray drying tower is connected with an inlet of a cyclone separating device, and the airflow type atomizer is fixed at the top end of the drying tower by an atomizer fixing device, wherein the atomizer fixing device comprises a fixing rod, an axial fixing bolt, three radial fixing bolts, three sealing gland fixing bolts and a sealing gland. The axial fixing bolt is arranged at the end of the fixing rod, the three radial fixing bolts are uniformly distributed around the fixing rod and are perpendicular to the fixing rod, the three sealing gland fixing bolts are uniformly distributed at the circumference of the fixing rod and are 3 to 10 centimeters away from the axial direction of three radial fixing bolts.

Description

technical field [0001] The invention relates to a drying method and a device for an agricultural fungicide, in particular to a drying method and a device for a complex state mancozeb wettable powder. Background technique [0002] Complex mancozeb is a high-end product among mancozebs for agricultural use, and has better performance than ordinary mancozeb. The drug effect of its product is stable, long-lasting, and harmless, but after the complexation reaction, the slurry has a large water content and is difficult to dry. At present, manufacturers mainly use bottom spray air drying, such as figure 2 shown. The complexation reaction slurry enters from the bottom of the drying tower, atomizes at the bottom of the drying tower through the atomizer and exchanges heat and mass with the heated air, and the atomized material is overcome in the drying tower under the action of the induced draft fan. Gravity, flow upwards. After the materials are separated by cyclone and collected...
